Overview

Tirzepatide is a first-in-class dual glucose-dependent insulinotropic polypeptide (GIP) and GLP-1 receptor agonist developed by Eli Lilly. It works through two complementary pathways, which may explain its superior efficacy compared to GLP-1-only agonists.

The SURMOUNT clinical trials showed average weight loss of 20-25% of body weight — significantly more than semaglutide. Sold as Mounjaro (diabetes) and Zepbound (weight management). It represents the current frontier of pharmaceutical weight management.
